Section 1. Annual Meeting.  The annual meeting of the stockholders shall be held
within six months of the end of the  corporation's  fiscal  year as fixed by the
board of  directors  for the  purpose of electing  directors  and for such other
purposes as may be determined  as  hereinafter  provided.  The hour and place of
such  meeting and the  purposes for which such meeting is to be held in addition
to that  specified  above  shall  be  determined  in each  year by the  board of
directors  or, in the absence of action by the board,  by the  president.  If no
annual meeting has been held in the period fixed above, a special meeting may be
held in lieu thereof with all the force and effect of an annual meeting.

Section 2. Special Meetings.  Special meetings of the stockholders may be called
at any time by the president or by the board of directors and shall be called by
the clerk, or in case of the death, absence, incapacity or refusal of the clerk,
by any other officer,  upon written  application of one or more stockholders who
hold at least  one-tenth  part in interest of the capital stock entitled to vote
thereat. Such application shall specify the purposes for which the meeting is to
be called and may designate the date, hour and place of such meeting,  provided,
however, that no such application shall designate a date not a full business day
or an hour not within normal  business hours as the date or hour of such meeting
without the approval of the president or the board of directors.

Section 3. Place of Meetings.  Meetings of the stockholders may be held anywhere
within, but not without, the United States.

Section 4. Notice.  Except as hereinafter  provided, a written or printed notice
of every  meeting of  stockholders  stating the place,  date,  hour and purposes
thereof  shall be given by the  clerk or an  assistant  clerk  (or by any  other
officer in the case of an annual meeting or by the person or persons calling the
meeting  in the case of a special  meeting)  at least ten (10) days  before  the
meeting to each  stockholder  entitled to vote  thereat and to each  stockholder
who, by law, by the articles of organization or by these by-laws, is entitled to
such notice,  by leaving such notice with him or at his residence or usual place
of business or by mailing it, postage  prepaid,  addressed to him at his address
as it appears upon the records of the corporation. No notice of the place, date,

                                    -- 4 --

hour or purposes of any annual or special meeting of stockholders  need be given
to a stockholder  if a written waiver of such notice,  executed  before or after
the meeting by such stockholder or his attorney thereunto  authorized,  is filed
with the records of the meeting.

Section 5. Action at a Meeting.  Except as otherwise provided in the articles of
organization,  the  presence of a quorum  shall be  separately  determined  with
respect to each matter to be acted on at any meeting of stockholders,  and shall
consist  of the  holders of shares  having  the right to cast a majority  of the
votes which may be cast with respect to such  matter.  Though less than a quorum
be present,  any meeting may without further notice be adjourned to a subsequent
date or until a quorum be had,  and at any such  adjourned  meeting any business
may be transacted which might have been transacted at the original meeting.

When a quorum is present at any meeting,  the affirmative  vote of a majority of
the shares of stock  present or  represented  and voting shall be necessary  and
sufficient to the  determination  of any questions  brought  before the meeting,
unless a larger vote is required by law, by the articles of  organization  or by
these by-laws,  provided,  however,  that any election by stockholders  shall be
determined by a plurality of the votes cast by the stockholders entitled to vote
in such election.

Except as  otherwise  provided by law or by the articles or  organization  or by
these by-laws,  each holder of record of shares of stock entitled to vote on any
matter  shall  have one vote for each  such  share  held of  record by him and a
proportionate  vote for any fractional  shares so held by him.  Stockholders may
vote either in person or by proxy.  No proxy  dated more than six months  before
the meeting  named  therein shall be valid and no proxy shall be valid after the
final  adjournment  of such  meeting.  A proxy with respect to stock held in the
name of two or more persons  shall be valid if executed by anyone of them unless
at or prior to the  exercise  of the proxy the  corporation  receives a specific
written  notice to the contrary  from anyone of them. A proxy  purporting  to be
executed  by  or on  behalf  of a  stockholder  shall  be  deemed  valid  unless
challenged at or prior to its exercise and the burden of proving its  invalidity
shall rest on the challenger.

Any election by  stockholders  and the  determination  of any other questions to
come before a meeting of the stockholders  shall be by ballot if so requested by
any stockholder entitled to vote thereon but need not be otherwise.

proposal  to  be  acted  upon  at an  annual  meeting  of  stockholders  of  the
corporation  must be provided to the  corporation  at least 120 calendar days in
advance  of  the  date  of  the  corporation's   proxy  statement   released  to

stockholders.  Written notification of any stockholder proposal to be acted upon
at any  meeting  of the  stockholders  of the  corporation  other than an annual
meeting must be provided to the  corporation  at least 180 calendar  days before

directors following the annual meeting of the stockholders shall be held without
notice  immediately  after and at the same  place as the  annual  meeting of the
stockholders  or the  special  meeting  held in lieu  thereof.  If in any year a
meeting  of the  board of  directors  is not held at such  time and  place,  any

a  subsequent  date or until a quorum be had.  When a quorum is  present  at any
meeting a majority of the directors present may take any action on behalf of the
board  except to the extent  that a larger  number is  required  by law,  by the
articles or organization or by these by-laws.

Section 10.  Action  Without a Meeting.  Any action  required or permitted to be
taken at any meeting of the  directors may be taken without a meeting if all the
